“…Furthermore, according to ref. [29], the application of digestate facilitates the settling of phosphorous and metals such as copper and zinc, consequently diminishing their discharge into surface waters preventing eutrophication or algal bloom. Within the anaerobic digester, the principal components undergoing alteration are carbon and nitrogen that result in an 85% reduction in biological-oxygen demand [30].…”

Energy availability is a pivotal driver in fostering sustainable socio-economic development. However, sub-Saharan Africa (SSA) grapples with paradoxes headlined by abundant energy resources but with the world’s lowest access to clean energy index per capita. Faced with a lack of access to clean energy sources like electricity, rural areas in the majority of SSA countries almost exclusively depend on biomass-fuels, mostly fuelwood, leading to heightened respiratory health risks as well as environmental degradation and accelerated climate change. As an alternative, this review investigates the potential of animal manure as a sustainable energy resource for rural SSA households, emphasising its utilisation as a feedstock for biogas production using anaerobic digestor technology. Results show that despite the abundance of literature that reports on successes in lab-scale bioreactor optimisation, as well as successes in the initial rollout of biogas biodigester technology in SSA with the help of international collaborators, the actual uptake of biogas bioreactor technology by rural communities remains low, while installed bioreactors are experiencing high failure rates. Resultantly, rural SSA still lags significantly behind in the adoption of sustainable clean energy systems in comparison to rural communities in other regions. Among some of the hurdles identified as driving low technology assimilation are onerous policy requirements, low-level government involvement, high bioreactor-instalment costs, the lack of training and awareness, and water scarcity. Prospects for success lie in innovative technologies like the low-cost portable FlexiBiogas system and private–public partnerships, as well as flexible energy policy frameworks. Bridging the knowledge-implementation gap requires a holistic approach considering cultural, technological, and policy aspects.

The continuing increase in dairy cattle farming poses a significant threat to the environment due to the release of greenhouse gases (GHG) from uncontrolled manure generation. Waste valorisation of dairy cow manure (DCM) through anaerobic digestion (AD) provides an avenue for simultaneously managing DCM and mitigating climate change through renewable energy. This review provides an overview of DCM production and the potential use of the AD processes for waste management and renewable energy generation in Fiji. Fiji dairy farms are geographically unevenly distributed and have considerably small herd sizes. With pretreatment techniques, biogas production from DCM at these farms has the potential to be optimised, economically feasible, and viable. Biogas production from DCM can be enhanced by approximately 125% with pretreatment techniques. Hence, this study reviews various pretreatment methods, their economic and environmental benefits, and AD's general challenges and limitations. This research reveals a need for further investigation into the optimisation of biogas and bio-methane potential of DCM, specifically with the economic viability and the environmental considerations of implementing these techniques at Fijian dairy farms.
